Abstract:
The report covers an investigation of the influence of fuel constituents during storage on thermal stability of JP-6 and other high temperature fuels. The major objectives of the program were satisfied by the successful development and evaluation of several methods utilizing radiotracers to determine the causes of thermal instability as well as predicting thermal stability quality of high temperature fuels during storage. Ninety-four test blends of 12 fuels and 9 radioactive fuel compounds were prepared and tested in the evaluation of a microscale thermal stability procedure developed for the purpose of determining the contribution of selected fuel components to thermally induced deposits. Eight-eight of these test blends were retested after 26 weeks storage at 130F to determine the effect of storage upon deposit-forming tendencies. Analysis of the data obtained in this study resulted in a further study of thermal decomposition of a fuel antioxidant additive. An investigation of several variables associated with an in situ hydrogenation method using tritium as the index of reactivity was completed as an effort to develop a sensitive and accurate analytical technique for very low concentrations of olefins in hydrocarbon fuels. In addition, initial steps were taken toward obtaining or synthesizing radioactive materials and reference standards essential to a continuation of this program along a similar line of approach.
